2 Claims. (Cl.9'7--172) Figure v6 is a perspective View of an adjusting member.

In the embodiment of the invention selected for illustration, the cultivator includes a central beam provided with a head I2 to which are connected two side beams I4. These side beams are pivotally connected at I6 with the head I2 for adjustment about vertical axes. Shanks I8 are attached to the rear ends of the respective beams I0 and I4, which beams support the ground tilling plows or tools 20.

Handles 22 are fixedly connected at 24.with the beam III, which handles are additionally supported by braces 26 bolted to the handles and to the central shank I8.

To the beam Ill are connected two angles 30, as by a bolt 32. These angles are so positioned as to provide horizontal arms 34 lying in a common plane and projecting laterally from the beam I0. Brace members 36 are bolted at 38 to the handles 22, and bolts 40 extend through the feet 42 at the lower endsof the braces 36 and the arms 34.

Angle members 44 are bolted at 455 to the beams I4 and are twisted to provide arms 48 lying in horizontal planes and pivotally connected at 50 with bars 52 lyin underneath the arms 34. These bars are slotted at 53 for the reception of the bolts 4|]. Thus the side beams l4 may be pivoted toward and away from the beam It! to change the spacing between the plows 20. When the beams have been adjusted to desired positions, the bolts 40 are tightened to hold the bars 52 against accidental shifting.

Provision is made for raising or lowering either side beam I4. It frequently happens that the field under cultivation is such that one plow must follow a furrow or must cultivate an elevation, such as the edge margin of a bed or other high ground formation. When the side plows are engaging deeper than the central plow, the implement is difiicult to control and tends to oscillate I neath the arms.

laterally. To adjust the side plows 20 vertically, Figure 5 illustrates one of the bars 52 as being arranged above one of the feet 42, and a washer 54 is interposed between the bar and foot 42.

I This will elevate the beam I4 on that side of the implement. Either or both beams may be adjusted vertically in the same manner, and additional washers may be'employed in cases where the beam or beams are to be lifted considerable amounts.

The bars 52 may be located either above or below the arms 34. Under ordinary cultivation con ditions, these bars are preferably arranged under- Figure 4 illustrates one of the side beams in an elevated position through insertion of a washer 54.

Without further elaboration, the foregoing will so fully explain my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.

I claim:

1. A cultivator comprising a central beam having a head, a pair of side beams pivoted to the head and extending out angularly from the respective sides of the central beam, plows on the side beams, an angled member bolted to each side beam and extending inwardly toward the central beam, a slotted member pivotally connected on one end to each angled member, angled members connected to the central beam and extending outwardly therefrom toward the side beams, and bolts connecting the last mentioned angled members to the slotted members whereby to adjust the slotted members and side beams with reference to the central beam.

j 2. A cultivator comprising a central beam having a head, a pair of side beams pivoted to the head and extending out angularly from the re spective sides of the central beam, plows on the side beams, handles connected to the central beam, an angled member bolted to each side beam and extending inwardly toward the central beam, a slotted member pivotally connected at one end to each angled member, angled members connected to the central beam and extending outwardly therefrom toward the side beams, braces from the handles to the latter angled members, bolts connecting the latter members, and braces to the slotted members whereby to adjust the slotted members and side beams with respect to the central beam, and means for adjusting said side beams vertically and independently.
